ABSTRACT:
A sink strainer assembly includes a strainer body adapted to fit in the drain opening of a sink having a threaded bore and an annular shoulder in its interior, a strainer basket having a bottom wall formed with a bore, a post formed with a top handle, a bottom threaded portion and a reduced diameter middle portion, and a rubber stopper having a bore of the same diameter as the middle portion of the post. The strainer basket is mounted to the post by inserting the post through the bore in the strainer basket so that its top handle extends atop the bottom wall and the middle section of the post extends beneath the bottom wall. The rubber stopper is then forced over the threaded bottom portion of the post and seats within the middle portion in contact with the underside of the strainer basket to mount the strainer basket to the post. The strainer basket, post and stopper are thereafter inserted as a unit into the strainer body where the threaded bottom portion of the post mates with the threaded bore of the strainer body. The post is rotatable to lower the rubber stopper into sealing engagement with the annular shoulder to fill the sink, or raise the rubber stopper from the annular shoulder for draining.
